At an archaeological dig in the Middle East, Hercule Poirot finds himself investigating the death of Lady Boynton, the wife of the expedition leader Lord Boynton. She had been visiting with her three children and their...展开now elderly nanny and was greatly disliked by virtually everyone who came into contact with her. Other visiting the site include Dr. Sarah King, Jefferson Cope, Lord Boynton's son Leonard, Dame Celia Westholme and Dr. Gerard. From all accounts, the dead woman was nothing short of cruel to her children and others put in her care. This proves to be the motivation underlying her murder.
